Rockingham Landfill Gas Abatement Facility

Rockingham Landfill Gas Abatement Facility is a landfill gas electricity generation project located at the Millar Road Landfill Facility in Baldivis, approximately 10km southeast of Rockingham in Western Australia. Registered in August 2013, the project operates within the footprint of the existing waste facility. The surrounding Baldivis and Rockingham region is characterized by a mix of peri-urban residential development, market gardens, and industrial land use.

Electricity generation from landfill gas projects involve capturing and combusting methane, a highly potent greenhouse gas naturally released by decomposing organic matter, to generate electricity. This project utilizes an extensive gas collection system to capture and combust gas generated at the landfill from both legacy and non-legacy waste, ensuring methane that would otherwise be freely vented into the atmosphere is converted into energy.

The region experiences a Mediterranean climate with a moderate annual rainfall averaging between 654mm and 788mm, with the majority falling during the cool winter months. Local soils are predominantly deep, highly permeable sand and limestone typical of the Swan Coastal Plain's Spearwood Dune System, which are generally known for their high pH levels and low water-holding capacity.

Over its lifecycle, the project has undergone several methodology and proponent variations to align with updated baseline standards. Originally managed by AGL Energy Services, project operations transitioned to Sustainable Energy Infrastructure Trust in 2019, and subsequently to LMS Energy Pty Ltd in March 2022. LMS Energy is one of Australia's largest landfill biogas operators, managing site infrastructure that dates back to the early 2000s. In February 2023, the project reached a major milestone when it successfully completed its April 2015 carbon abatement contract (CAC203884).
